PARKING LIGHT.

Application filed September 26, 1921. Serial No. 503,858.

To all whom/ it may concern: i

Be it known that I, ANGUS R. Gnoss, a

citizen of the United States, residing at Baltimore, in the county ofBaltimore City and State of Maryland, have invented certain new anduseful Improvements in Parking-Lights; and I hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, which form part of thisspecification.

This invention is a novel parking light for use on autpmobiles, but alsoadapted for use in other places and for other purposes. The object ofthe invention is to provide a cheaply constructed, and securely fastenedupon the fender or other support.

Further objects of the invention are to provide novel means for makingthe proper electric connections between the electric llght bulb and anelectric circuit when the light is inserted in the lamp.

I will explain the invention with reference to the accompanying drawingwhich illustrates a simple form of the lamp and the electricalconnections of the bulb and refer to the claims for summaries of thenovel 'features of the inventionand the novel con parts. for whichprotection is desired.v

In said drawing:

as attached to the fender of a vehicle.

Fig. 2 is a longitudinal vertical section through the lamp casingdetached.

Fig. 3 is a transverse vertical sectional view thereof on the line 3-3Fig. .1.

Fig. 4 is an end view of the lamp casing.

Fig. 5 is a greatl enlarged sectional view through the lamp s owing theelectrical con nections:

The lamp shown comprises a preferably short cylindric casing 1 open atboth ends, but providedwith an annular 'seat 1 in each end for atransparent jewel or glass 2, which is preferably confined therein by asplit sprmg-ring 2 seated in an-annular recess 1 in the end of thecasing exterior to the jewel.

The casing is also provided with a hollow depending stem or T1" thelower endofthe bore of the T being internally threaded for, a shortdistance-as at 1*. In the body of the casing at the u per end of .thebore of the"? are formed s ort bayonet slots 1 for the engagement of theusual side studs or ins on the shank of the electric li ht bulb which isof usual construction. T 's light is engaged with the bayonet slots byremoving one or both of the jewels 2 (which may be easily done byspringing out the "rings 2) and then inserting the lamp in place; thenthe casing is closed by replacing the jewels and rings. It will be seenthat the lamp socket having the bayonet slots 1 can be and preferably isformed as an integral part of the lamp casing 1. Such casings can bedrop forged.v 3

Screwed into the lower end of theT 1 of the casing is a tubular shankmember 4' which has an internally projecting annular flange 4 at itslower end and which is externally threaded and screwed'directly into thecasing T as far as the threads 1 permit, thereby securely fastening theshank member 4 to the casing.

The lower part of the shank member is 7 adapted tov extend through anopening in the fender F or'other support upon which the lamp is to bemounted (see Figs. 1 and 5), the lower end of the T 1 rests upon the topof the fender, then it is secured theretoby a nut 5. In order to make asimple eflicient electrical connection and circuit through the light Lwhen laced in the casing, I employ the novel diavices shown. Arrangedaxially within the shank member. 4 is a metal member 6 having an axialrecess 6 Fig 1 is a s1de view of the complete lamp in its upper end, andhaving its lower ex ternally threaded and above the threaded whichengagesthe under surface of the lower end of the member 4: or flange 4*and is clamped thereagainst by a nut 6 screwed onto the threaded portionof the member" 6. By tightening nut 6 the washers W W are clampedagainst the flanges 4 which extend therebetween, thus securely centeringand holding the member 61into place, and the washers at the same timeeflectually'insulate the latter from direct contact with the metal ofpart 4:, as indicated in Fig. 5.

Telescoping the upper end of member 6 the bore 6 and member the upp is ahollow contact member 7, which is pref-- erably slidably confined in theupper end of the member 6 so as to telescope therewith, and isnormallyprojected outwardly by an expansion helical sprin 8 arrangedwithin To prevent member 7 being disengaged from member 6, the lower endof the cap 7 may be slightly flanged outwardly I as indicated at 7, ander end of the part .6 slightly inturned as indicated at 5.

The contact member 7 normally projects upwardly in the shank 1 so thatwhen the lamp L is. inserted in the casin and its shank properly engagedwith the s ots 1 the lower contact on the end of the lamp shank (asusual) will contact with the member 7 and thus close a metallic circuitfor the electricity through the lamp. The current is supplied through anelectric conductor C which maybe connected-with any suitable source ofelectricity, and may be clamped between the nut 6 and a nut 6 screwed onthe lower end of member 6 below the nut 6; the return circuit being madethrough the metal of the lamp, and shank and supports in the usual wellknown manner.

It will be seen that the invention provides a very simple inexpensivelamp; that a very small bulb may be used therein; and that the means formaking the electric circuit through the light are very simple and can bereadily assembled in and connected with the shank member before it isconnected with the casing.
